Vulcan Patents

Vulcan S/N 463, manufactured in 1908, sporting its then valid patent…wait, the patent number’s wrong, it should be 378,745, as you can see below.

Vulcan was an innovator in pile driving equipment for more than a century. This history can be documented in part by the patents that were issued to Vulcan’s people, in addition to those which it acquired externally. We also include patents that were related to Vulcan either because they were issued to a Warrington or they related to a Vulcan product but were never formally assigned to the company.

We also have experience in acting as an expert witness in patent disputes; contact us if you are interested.
